Hi,
I've an issue with my L502X.
The NVIDIA driver (latest version, the chip is a Geforce 525M ) is crashing frequently (let's say, every minute or so) and sometimes the laptop freezed completely. The issue happens mostly when I have an external screen plugged in in the HDMI port.
After few days the video card issue started, the HD also died, so I replaced the hard drive (warranty is expired), reinstalling a clean OS (8.1 pro x64) but the issue still happens. Following indication from dell support on twitter I also installed the latest drivers for the chipsed (HM67) and the integraded video card drivers (HD3000), without any improvement.
I was suspecting overheating as the cause of the issue, but the GPU temp (both intel and nvidia) never goes above 60°C, CPU temp went up to 86°C.
Any idea about what can cause the issue?
